Getting Parent and child grouped under parent

Is there a possibility to get the search results grouped with child - parent relationship. Suppose i have a parent A having child B & C and both B & C child have childs D,E,F. I want all these child results to be grouped under the same parent A. Is there a possible way to query the Rest API and get this result. A /\ B C /\ \ D E F This is example tree structure i need all these results categorized under same parent A without using any custom field. Please help me with a sample query if it is possible.

You can use the childField and parentField query parameters and parentResult when looking at the returned results. You may need custom fields if you don't already have a field on your child results that contains a parent result unique id.
